Runs on the big three desktop platforms (Mac, Windows, Unix)
Required to run in a headless enviornment, as well as a desktop image
Talks to the world thru some standardized XML-RPC protocols. The Blogger API is a subset of the MetaWeblog API. (Look at XML-RPC Server for some Squeak related overview and code).

Cross authoring of blogs
Ability to comment posts. The comments need not be threaded
SBlog server should also have the capability of being a stand alone solution. Howerver, because most blogs are served as static HTML files, it should be straightforward to "turbo-charge" the SBlog server by placing it behind something like Apache. Apache serves the static content, SBlog handles the heavy lifting.
This same idea may play into having 'swappable' object store, where the SBlog server may use an RDBMS as a backend to physically store the database information, or an object oriented database. This idea is not strict; a clever object store for persistent data may be implemented at the teams discretion. The case may be made for storing all data within the image, that will be part of the discussion of the contest rules.
Overall, the idea should be to make a simple, lightweight, fast server that someone who is familiar with what should be done can grok in a short amount of time. The SBlog challenge provides the outline; the contest will provide the documentation by means of design decisions made by the programming teams. The comments and correspondence among team members will be placed in a public place, such as this Swiki, so that others may learn.
